Priority Queuing Strategies In high-throughput systems, processing certain tasks ahead of others is critical. For instance, an order notification system might distinguish between VIP customers and standard users. Standard queues distribute messages based on arrival order (FIFO). To handle business-critical scenarios where specific messages requ ...
